My invention relates particularly to that class oflubricant compressorsthat have a.

hand operated pump arranged to receive lubricant from a reservoir and toforce it through a suitable outlet conveyor to one or more bearinglubricating devices, and is especially directed to that type oflubricant employed as central feed system compressors.

The principal objects of my invention are to provide a lubricantcompressor that is flexible in its adaptation to different conditionsand positions for use, that is of simplified construction, and that isinexpensive to manufacture. v I Other objects of my invention are toprovide a lubricant compressor inwhich the parts subject to wear maybereadily removed and replaced and the cooperative parts may beConveniently adjusted to adapt them to varying conditions of use. y

' Further objects of my invention are to provide a compression unit thatmay be adapted to compress either oil in fluid or semifluid state, orgrease in any desired plastic condition with equal facility.

'My invention includes a compressor unit embodying my invention that maybe provided with a reservoir formed in unitary relation therewith, orthe reservoir may be integrally attached thereto, or the compressor maybe inserted in the bung ofia container or drum ser-ving itself as areservoir from which the contents may be directly pumped bysaidcompressor. 7 r

Specifically stated, the form of my invention as hereinafter describedcomprehends a cast compressor unit havinga bore in which a bushingproviding a valve seat anda plunger bore'may be forced and having aplurality of relatively spaced lugs projecting therefrom with any one ofwhich aplunger operating lever maybe pivotally connected for-theconvenient reciprocation of a plunger in thebore of said bushing. Myinvention also includes all of the various novel features ofconstruction and arrangement as hereinafter more definitely I .th a compny ng dra n Figure is a perspective view of a lubricant com v pressorconstructed in accordancefvvith my invention; Fig. 2 is a fragmentarycentral. l

Thepump-casing 2 is provided atone end with the flange 6serving asa'means'by which the structure may loeattach ed to any form ofsupport7fofthe bolts 9. i

The forward end of the provided with a plurality' of lugs 10,11, 12 and13, each having suitably provided apertures 15 through which a pintl a-,b-

tended. Said casing 2 is provided with aremovable andreplaceablabush'ing 17 having the bore 19 connected by the aperture20with the inlet 4 and said bushing '17 is providedat its inner end withconical seat "2 1 for the ball check-valve-22 which is normally pressedpump-casing2 is- .925 against its seat the spring 23, the tensionTheforward end of the bushing17 is provided with a'stutiing-box 29having the gland tends into the bore 19 of the bushing 17.

that said lever extends upwardly, as indicated in said figure; or itslink 37 may be connected with the lug so that said lever 35 extendsdownwardly in a position directly opposite to that shown in Fig. 1; orthe link 7 37 may be connected with either of the lugs 1 1 and 13 sothat the position of the lever 35 may extend horizontally either towardsthe right or the leftas desired, andin accordance with the varyingconditions that may be found at the place where the lubricant compressoris to be employed.

For instance, if said compressor must occupy a position close to thet1oor,,then the le- Ver 35 will extend upwardly; if, on the other hand,it must be placed in an elevated -positien, the lever may be extendeddownwardly; and similarly, if there should be anything in the way of theactuation of the lever, it may be extended in any other position, asdesired. Obviously, the arrangement shown and described is highlyflexible in its mode of operation. H I

The lubricant compressor body 1 is conveniently provided with the cover42 which may be clamped down upon the upper perimetral edge of the body1 to form a tight joint, said cover being provided with the oppositelyextending bosses 43 and45, the former having the aperture 46 and thelatter having the slot 47 which respectively receive the swing-bolts .49and 50 having the wing-nuts 51 and 52 respectively. The swing-bolt 49 isprovided with the pintle 53 extended through the lugs 54 which projectfrom the wall of the bodyl and the swing-bolt 50 is connected by thepintle 55 extended through the lugs 56 projecting from the oppositewallof said body imilarly, the remaining walls of the body 1 may beprovided with lugs 57 so that the swing-bolt 49,"which serves as a hingefor the cover 42 permitting it to be swung open, as indicated by thedot-and-dash lines in Fig. 2,

may be engaged with any of the lugs on the foursides of the body 1, sothat the cover 42 may open 111 any desired posltion with respect tothefour sides of said body. As will be obvious, the swing-bolt 50 will bedisposed opposite to the position of the swing-bolt 49 irrespective ofthe posltion of the latter, and

in order to openthe cover 42 the wing-nut 52 of the swing-bolt 50 may beloosened and swung through the slot 47 and permitted to invention,

hang pendant, as indicated in dot-and-dash lines in Fig. 2. Obviously,the above-noted arrangement provides for the cover to be opened in anyposition to aiford the greatest convenience.

i As shown in Fig. 1, the outlet 5 may be connected with line piping 60,which may include the T-fitting 61 for the convenient attachment of apressure-gauge 62, which indi cates the pressure on the lubricant beingforcedthrough the outlet 5 and the line connection.

In the form of my invention shown in Fig. 6, which is particularlyadapted for grease or heavy lubricant, the lubricant-containing body 71may be formed of a tubular shell integrally connected with the 'pu1np-casing' 72 which has the upturned flange 73 forming a pocket into whichthe lower end of the tubuh lar shell of the casing body 71 may beengaged in any suitable manner. In other respects the pump-casing 72 issimilar to the pump-casing 2 shown and described with respect to Figs.1, 3 and 4. I

The body 71 may preferably be exteriorly threaded at its upper end toreceive the threaded cap 75 through the central aperture 76 of which thestem 77 having the operating handle 78 of the plunger 79 extends, saidplunger 79 being normally forced downwa-rdly 'upon the lubricantcontained in the body 71 by the spring 80, so that there is alwayssuihcient pressure upon the lubricant to force it through the inlet intothe bore of the pump and in position to be forced forwardly through theoutlet by the plunger.

The form of my invention shown inFigs. 7 and 8 is particularly adaptedto'be engaged'in the bung of a drum or container for lubricant, whichmay include the side walls 82 and the head 83 provided with the threadedbung-ring 85; In this form of my the pump-casing 92 has the bore 93 andis provided with the inlet 94 and the outlet 95 which is connectedthrough the passageway 96 extending parallel through said casing withthe pump-bore 93 and connected by the pipe line 97 to any desired pointof delivery.

Said pump-casing 92 is exteriorly threaded i at 99 to engagethe threadsof the bung-ring threaded relation with said bung-ring 85.

This pump-casing 92 is providedwith attachment plugs 110, 111', 112 and113 projecting forwardly from the forward face of the hexagonal bosstoafford convenient attaching means for the link 115, to which the lever116 may be connected to actuate the plunger 117. I V

My invention is advantageous in that the lubricant compressor may beprovided with a pump-casing which may be formed of cast metal and thebore thereof be provided with ata when worn.

I do not desire to limit my invention to the precise details ofconstruction and arrangement as herein set forth, as it is obvious thatvarious modificationsmay be made therein without departing from theessential features of my invention as defined in the appended claims.
